SPECIFICATION formingpart of Letters Patent No. 704,714, dated July 15,1 902.

Application filed October 11, 1901. Serial No. 78,308- (No model.)

To all whom it may concern.-

Be it known that I, AUBIN A. LAFOREST, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Attachments forSpectaclespf which the following is a full, clear, and exactdescription, reference being had to the accompanyin g drawings, formingpart of this specification.

My invention relates to an attachment tacle-temples that rest in therear of the wearers ears.

The object of the invention is to provide means whereby a bearing ofgreater width against the wearers ears will be furnished to avoidcutting action by said hooks into the ears and also to furnish morecomfortable bearing against the ears.

Myinvention consists in features of novelty hereinafter fully described,and pointed out in the claims.

Figure I is a perspective view of a pair of spectacles equipped with myattachment. Fig. II is an enlarged detail view of one of the hooks ofthe spectacle-temples, the attachment being shown in longitudinalsection thereon. Fig. III-is a cross s'ectional view taken on line IIIIII of Fig. II.

1 designates a pair of spectacles having temples 2, that are providedwith hooks 3, hearing at their ends knobs 4.

5 designates curved channeled grooved flexible plates containingapertures 6, that receive the hooks of the spectacle-temples and providefor the threading of the plates onto said hooks. The plates 5 arepreferably of spring metal and occupy-positions within the hooks 3andare of considerably greater width than said hooks, thereby providing amuch greater bearing-surface againstthe rear of the ears of a personwearing the spectacles, and thereby avoiding chafing of the wearers carsby contact therewith and obviate the cutting action so frequentlyexperienced by wearers of spectacles consequent upon the bearing of thetemple-hooks against the ears. The attachment of the plates to the hooksis sufliciently free, as shown in Fig. II, to permit of lateral movementthereof, so that the plates will always adjust themselves properly tothe wearers ears and remain in settled positions against the earsirrespective of slight movement of the spectacle temples and hooks. I

I claim as my invention- 1. The combination with a pair of spectacleshaving a temple provided with a hook, of an attachment com prising aflexible plate loosely threaded at both ends onto the hook of saidtemple and lying on the inside of the curve thereof, and free fromengagement with said hook, intermediate the ends of the plate,substantially as and for the purpose set forth.

2. The combination with a pair of spectacles having a temple providedwith a hook, of an attachment comprising} a channeled plate looselythreaded at both ends onto the hook of said temple and lying on' theinside of the curve thereof, substantially as and for the purpose setforth. 3

'3. The combination witha pair of spectacles having temples providedwith hooks, of an attachment comprising aspring-strip threaded onto saidtemple-hooks at the insides thereof and so laterallyconnected' to thehooks that lateral movement of the strips is provided with respect tosaid hooks, substantially as described.
